No.163-SB ENAMELED WIRE STIFFNESS TESTER (SPRING BACK METHOD)
JIS (C3003), C3216-3, IEC-60851-3
- Insert one end of the wire sample into the stopper hole on the mandrel and hang a weight on the other end.
- Wind the sample around the mandrel three times at a rotational speed of 5–10 times per minute, mark the sample, and then remove the weight.
- Slowly unwind the sample from the mandrel and read the scale at the position where the mark is located to evaluate its softness.
